SNOWPLOW Filed Dec, l5, 1929 4 Sheets-Sheet 4 INVENTOR ATTORNEY PatentedJan. 20, 1931 PATENT OFFICE RAYMOND LEE HULSLAN'DER, OF WORTHINGTON,MINNESOTA p sNowrLow Application -led `December 13, 1929. Serial No.413,846.

-This invention relates to a snow plow, `the general object of theinvention' being to provide a scoop for scooping up the snow as the plowis pushed into the snow, with a con- B caved part for receiving ythesnow from the scoop and a wheel having blades thereon which pass overthe concaved part when the wheel is being rot-ated .so as to throw thesnow to one side of the road or the other, ac` cording to the directionof lrotation of ythe Wheel so'th'at the snow is not banked in the road,but is thrown to one side of the road.

Another object of the invention is to provide cutting blades on Vthewheel which exe tend forwardly of the other blades Aand act to dcutandloosen the snowbefore it is operated on by said other blades. Anotherobj ect of the invention Ais to` provide hinged wings for increasing thelength of the concave when the plow is `working in deep snow and toprovide a Apointed device on 'the hub of the wheel for preventing deepsnow from pressing against the front face of the wheel.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to 4'behereinafter fully described, illustrated in the accompanying drawingsand claims.

'In describing the invention in detail, reference will 'had to theaccompanyingvdrawings wherein likecharacters denotelike or'corresponding parts `throughout the several views, 'and in which :-w p

Figure 1 is an elevation, with parts in sec# tion, showing the plowattached'to atractor.

Figure 2 is a top pla-n view of Figure `1.

FigureB is a front view of the plow.

Figure 4 is av vertical sectional View through the plow.

Figure 5 is 'a rear view of the plow.

Figure 6 is a sectional detail view showing the means for driving thewheel of the plow from the tractor.

In these views, fthe numeral 1 indicates a housing having its sidessloping upwardly and inwardly to its fiat 1top`.2 andthe numeral 150 3indicates a "concaved part vattached to *the specifically pointedl outin the appended front of the housing at its lower end, and 4 indicatesa'scoop attached to the front edge of the concave and adapted to scoopup snow as the device is moved along so that the snow will enter theconcave. Side pieces 5 are connected with the `sides of the housing andthe ends of the 'concave andv scoop andk form groundengaging shoes.Abrace 6 extends from the bottom of the housing under the concave andscoop and acts to brace theparts. A horizontally arranged bearingmember? is fastened to the top ofthe housing and rotatably supports ashaft 8 to which the hollow hub of a wheel 9 is. fastened, the hubportion having it-scorners tapered to form the blades 10. "The wheel isarranged above the concave in such 'a manner that its blades will passover the same as fthe wheel is rotated. Flat blades 1l are fastened tothe wheel between the blades 10 and these blades are bent, as at 12,where they join the wheel, so that the major portions of the blades 11are in advance of Jhe wheel. Each vblade is sharpened or beveled on eachedge. A pointed -meniber'l is connected with the front face of thehuband is composed of substantially triangular shaped parts connectedtogether at their inner ends, with their small ends arranged adjacentthe point of connection of the blades 1'1 with the wheel.

A substantia'Hy L-`shaped wing 14 is hinged to the front of the housing,at each side there# of, thesewings forming extensions of the'conca-vewhen they are swung forwardly and when swung rearwardly,they will reston the sides of the housing so that the concave will be ofless lengththan when the wings are in forward position.

A pair of beams l5 have their front ends connected with the housing andtheir rear ends are adapted to be pivotally connected wit-ha part of atractorv A, as shown at 16, and a shaft 17 has its front end journaledto the rear face of the housing and carries a sprocket V18 over whichpasses a chainV 19 which also passes over a large sprocket 20 on the`rear end of the shaft 8 which carries thel `wheel 9. A shaft 2l isrotatably arranged in a housing V22 supported by the hangers 23 from thetractor, and this shaft 2l `is connectthrough the concave.

ed by the couplings, shown generally at 24, with the shaft-,17, so thatthe plow can have movement in relation to the tractor without affectingthe'driving connection between the shafts 17 and 2l. A sprocket 26 isconnected with the rear end of the shaft- 17 and a chain 27 passes koverthis sprocket and over a sprocket 28 on a shaft 29 arranged in a housing30. A pair of gears 31 is fastened to the shaft 29 within the housingand one of these gears meshes with an idle gear 32 in the heusing, whichin turn meshes with `a gear 33 loosely arranged on a shaf this shaft 34being driven from one of the drive shafts of the power plant of themotor by the chain and sprockets, shown generally at 35. A gear 36 isloosely arranged on the shaft 34 and meshes with the other `gear 31. Adouble clutch arrangement 37 is. slidably mounted on the shaft 34 and isadapted to be moved from a neutral position into engagement with eitherof the gears 33 or 36, so as to drive the shaft 29 in one direction orthe other. This clutch is manipulated by a shift lever 38. Y n

A worm gear 39 is fastened to therear end of the shaft 29 and mesheswith a worm gear 40 on a shaft 41 transversely arranged on the tractorand having the drums 42 atfits ends to which cables 43 are connected.YThese cables pass forwardly over the pulleys 44 at the front of thetractor and then pass downwardly and are connected with the front endsof the beams 15, as shown at 45.

A clutch 46, including a lever 47, is provided for connecting anddisconnecting the gear 40 with the shaft 41. The shaft 4 1 is alsoprovided with the brake means, shown generally at 48.

From the foregoing it will be seen that th plow can be raised andlowered when the shaft 41 is connected with 1the shaft 29, so that theplow can be adjusted to pass over obstructions or can be held in raisedposition when it is being conveyed to and from the point of use and thatthe wheel of the plow is driven in either direction from the power plantof the tractor, though it will, of course, be understood that a separatemotor may be provided for driving the wheel, if desired. Y

The wheel will remove the snow from the concave and throw it a distancefrom thek road as the blades 10 on the wheel pass This will preventbanks of snow being formed on the. sides of the road. The blades 11 actto cut the snow in front ofthe wheel and loosen the same so that theblades 10 can properly operate on the same and the scoop Vwill pick upthe snow and cause it to pass into the concave. When the plow isoperating in deep snow, either or both wings should beraised to increasethe length of the concave, as shown in Figure 3, though these wings arenot needed in light tion that the advantages and novel features t 34 inthe housing,

snow. The pointed device 13 also acts in deep snow to cut the snow fromin front of the hub of the wheel and prevents this snow from retardingthe forward movement of the plow. The rapidly revolving wheel, havingits blades Vpassing through the concave, will set up a centrifugal forcewhich acts to throw the snow a considerable distance away from the road.

It is thought from the foregoing descripofthe invention will be readilyapparent.

It isto be understood that changes may be made in the construction andin the combinationv and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.
